Origin
Meaning and origin of Attilio
The surname Attilio is of Italian origin, derived from the Latin name Atilius, which itself is rooted in the Roman family name Attilius. It is believed to have originated in the ancient Roman era, possibly as early as the 5th century BC.
The name Atilius is thought to be derived from the Latin word "ater," meaning "black" or "dark," suggesting that the original bearer of this name may have had a dark complexion or dark hair. Alternatively, it could also be related to the Latin word "attilus," which means "fattened" or "well-fed," implying a connection to wealth or prosperity.
One of the earliest recorded instances of the name Attilio can be found in the Liber Pontificalis, an ancient book of biographies of the popes. It mentions an Atilius who served as a papal legate in the 6th century AD. Additionally, the name appears in various medieval manuscripts and records from Italy, indicating its long-standing presence in the region.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Attilio surname at the time of the 2020 Census, not any inherent property of the name itself.
